The 1999 Pontiac Trans Am Convertible with the WS6 package is a true American muscle car icon, offering a thrilling open-air driving experience combined with serious performance.
At its Heart: The LS1 V8 Under the distinctive functional Ram Air hood lies the potent 5.7-liter LS1 V8 engine. In its 1999 WS6 tune, this engine produced 320 horsepower and 335 lb-ft of torque, an impressive leap from the standard Trans Am. This power is delivered to the rear wheels, offering exhilarating acceleration and a true muscle car feel. Depending on the original build, it could be paired with a smooth-shifting 4-speed automatic transmission or, for the purists, a engaging 6-speed manual gearbox.
The WS6 Performance and Handling Package The WS6 package, known as the "Ram Air Performance and Handling Package," was what truly transformed the Trans Am into a track-ready machine. This wasn't just about horsepower; it was a comprehensive upgrade that included:
Convertible Thrills As a convertible, this Trans Am adds another layer of enjoyment. With the power-operated soft top (often with a glass rear window) retracted, you can fully experience the roar of the LS1 and the rush of the open road. The aggressive styling, with its flared fenders, steeply raked windshield, and large rear spoiler, is even more dramatic with the top down.
Interior and Features Inside, the 1999 Trans Am Convertible offered a driver-focused cockpit. Depending on the specific car, you'd find supportive bucket seats, often in leather, and a dashboard designed for easy access to controls. Standard features typically included power windows, locks, mirrors, air conditioning, and a Monsoon audio system.
Rarity and Collectibility The 1999 Pontiac Trans Am WS6 Convertible is a relatively rare car. For the 1999 model year, only 1,002 WS6 convertibles were produced, with 646 being automatics and 356 being manuals. This low production number, combined with its iconic styling, powerful LS1 engine, and the sought-after WS6 package, makes it a highly desirable vehicle for collectors and enthusiasts alike. It represents the pinnacle of late-model Pontiac performance and a piece of American muscle car history.
